Definitions

  • the present invention relates to an anti-glare device according to the preamble of claim 1.
  • Anti-glare devices are preferred in the welding and Cutting torch technology used, but also found in the Military and entertainment industries their use. In the Radiation becomes the rule with these anti-glare devices filtered out above 780 nm (IR) and below 365 nm (UV) and only the radiation in the visible range is dimmed.
  • the switching time is in all of these anti-glare devices device-specific, i.e. depends on the particular construction, electronic circuit and the components used.
  • the anti-glare devices in use today due to extremely short switchover times and low operating performance out.
  • a device to create which can automatically recognize how long the lightening time should be in a specific case in order to To protect users of the anti-glare device safely, however not hindering his work rhythm.
  • this object is achieved with a device which the characteristic features of claim 1 has and in particular the absolute light intensity, respectively. Amount of light and the duration of welding recorded and these parameters logically and / or temporally using suitable electronics reasonably linked with each other, so that the lightening time adapt optimally to the circumstances.
  • the change the light intensity during the welding process and the length of the interruption in sweat recorded and evaluated.
  • the device according to the invention thus also allows the different Sweat arc brightness (caused by different currents, different materials, etc.) to consider for the control of the lightening time and creates a universal anti-glare device.
  • the anti-glare device according to the invention enables a disability-free working and guaranteed at the same time the necessary security with the professional Use of these devices.
  • the known anti-glare device shown in principle in Figure 1 has a sensor 2, which is in the user's field of vision generated amount of light detected and a corresponding Signal generated.
  • This signal is sent to detector electronics 3 supplied, which is essentially a threshold circuit includes.
  • detector electronics 3 supplied, which is essentially a threshold circuit includes.
  • the on / off signal generated by this threshold circuit is fed to an evaluation electronics 4, which This on / off signal is processed in such a way that a light protection filter 5 can be switched as quickly as possible.
  • control unit 6 which with a timer 7 and memory 8 is connected.
  • This control unit 6 detects the signal generated by sensor 2 directly and evaluates this further out.
  • this control unit determines 6 the intensity of the light striking the sensor 2 and generates a signal corresponding to this amount of light Value is stored in memory 8 in order - within predetermined limits - To extend the lightening time of the light protection filter 5 accordingly.
  • the signal generated by the detector electronics 3 is also fed to the control unit 6 and in for the expert obvious way with the signal of the sensor 2 logically and / or linked in time to the lightening time in the desired and / or to control necessary.
  • the detected and / or generated signals used to transition from dark to light to control during the lightening time, i.e. a leap resp. to create a grinding transition.
  • the detected duration of the welding process can be used and / or the course of the signal generated by sensor 2 recorded at the beginning, during and at the end of the glare phase and serve to generate a reset signal.
  • the slope of the Dark / light transition directly from the generated brightening time dependent. It goes without saying that with anti-glare devices, how they are used professionally by welders, a manual protection level setting is provided. According to the invention the protection level and their manual fine adjustment additionally for the control of the Steepness of the dark / light transition can be used.
  • Figure 3 shows an embodiment for the temporal and / or logical combination of the first and second switching signals.
  • the detector circuit 3 generated second switching signal of a logic OR circuit 12 fed and thus allows the immediate darkening of the Sun protection filter 5 in the event of a glare situation.
  • the on / off signal the detector electronics 3 is also one with the Timer 7 connected time counter 11 fed. This time counter is in turn connected to a multiplier circuit 9 and activates it during this blinding situation, in called the following blend phase.
  • the multiplier circuit 9 with that generated by the sensor 2 first switching signal fed directly and generates one corresponding signal value, which is stored in the memory 8.
  • the OR circuit 12 brightens the light protection filter 5 prevented until a corresponding to the memory content delayed RESET signal resets counter 11 to zero and thus deactivates the multiplier circuit 9.
  • the delay corresponds to the RESET signal in the present example the product of the time of the glare phase and the intensity of the glare.
  • the electronic wiring of the control unit 6 is in the Area of professional skill and can consist of both individual components, integrated sub-modules or a suitable one Microprocessor built.
  • the use of additional sensors 2 or storage units 8 for further development and optimization the anti-glare device according to the invention is for the Expert obvious.
  • the anti-glare device according to the invention is therefore universal applicable, i.e. allowed for spot and tack welding a quick and unhindered work rhythm and provides the Darkening during the afterglow time which is dangerous for the eyes Long-term welding safe.
